Well, this <http://www.pygame.org/wiki/GLSLExample?parent=CookBook> didn't
work...

I might have been referring to simple tests like:

>>> from OpenGL.GL import *
>>> glCreateShader
<OpenGL.platform.baseplatform.glCreateShader object at 0x02C03090>
>>> glCreateShader()
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    glCreateShader()
  File "C:\dev\Python25\Lib\site-packages\OpenGL\platform\baseplatform.py",
line 299, in __call__
    self.__name__, self.__name__,
NullFunctionError: Attempt to call an undefined function glCreateShader,
check for bool(glCreateShader) before calling

Simply missing something?
